The initial stage of the loss of the morphological stability by spherical particles during quasi-stationary crystallization has been analyzed numerically. Axial disturbances of arbitrary amplitudes have been considered. Boundaries of the regions of coexistence of different morphologies have been established. The hypothesis that the coexistence regions can be found from the maximum-entropy-production principle has been validated for diffusion growth conditions.
